In 2019,Green Chemistry included an article by Li, Zhuofei; Song, He; Guo, Rui; Zuo, Minghui; Hou, Chuanfu; Sun, Shouneng; He, Xin; Sun, Zhizhong; Chu, Wenyi. Formula: C7H5BrO. The article was titled 《Visible-light-induced condensation cyclization to synthesize benzimidazoles using fluorescein as a photocatalyst》. The information in the text is summarized as follows:
A mild strategy for visible-light-induced synthesis of benzimidazoles I (R = Ph, cyclohexyl, furan-2-yl, etc.; R1 = H, Me, Cl) was developed using aldehydes RCHO and o-phenylenediamines 2-NH2-4-R1C6H3NH2 as substrates. The use of an organic dye, fluorescein, as an innoxious photocatalyst provided a mild and inexpensive catalytic system to synthesize a series of benzimidazoles I in moderate to excellent yields. It was originally applied to this system to obtain benzimidazoles I. Besides, the catalytic system does not require an addnl. oxidant or metal which was good for the environment.o-Bromobenzaldehyde(cas: 6630-33-7Formula: C7H5BrO) was used in this study.
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.Formula: C7H5BrOIt is a key starting material in the total synthesis of an anticancer agent, (-)-taxol.
